Samsung’s first generation of smartwatches is officially ditching Android. SamMobile reports that the original Galaxy Gear is being upgraded to Tizen, the operating system used on the newer Gear 2 and Gear 2 Neo (but not the Gear Fit, yet another model released this spring.) Samsung has made a point of differentiating its software from stock Android — its various Android smartphones are loaded with design tweaks — but in this case, the main difference will be in added features; we and other reviewers found that the Tizen interface looked and operated very much like the Android one.
